Korean adjectives are curious beasts. They are in fact verbs that need to follow the same rules as all other verbs in the language. Therefore there is no real word for ‘tired’ but instead ‘to be tired’ which is pigon hada 비곤하다. We recognise the verb ‘hada – to do’ here don’t we?

Using this we can either put it at the end of the sentence as a verb, thus:

pigon haeyo – I am tired / you are tired / he is tired, etc. 비곤해요

Or, we can make a slight change and put it before a noun:

pigon han saram – A tired person 비곤한사람

Notice what the change was? That’s right, we add -n to the verb stem of ‘hada’ after having taken off the -da/ta
